A clock driver outputs first and second preferably complementary clock signals coupled to substantially equal capacitive loads. Before each clock state change, the clock driver briefly shorts-together the first and second clock signals, to equalize change on capacitive loads, which each assume a potential midway between high and low power supply levels. Charge from the logic high clock signal can thus be used to raise logic low level clock line, and vice versa, rather than draw power supply current. Substantial energy savings on the order of C·V·f is achieved, where C is effective capacitive load, V is power supply magnitude, and f is clock frequency. The clock driver includes first and second enhanced inverters (inverters that cannot enter short-circuit current mode) whose outputs are the first and second clock signals, and a transistor switch coupled between the inverter outputs. Turning on the transistor switch forces charge equalization.

Dynamic adjustment of offset between timebases of separated electronic circuits is provided based on an amount of time between synchronization events, wherein a synchronization event is an event involving communication across a separation between the separated electronic circuits in order to synchronize the timebases. The dynamic adjustment can be dynamically or adaptively adjusting a margin of error to account for drift that may have occurred since a prior synchronization event. Adjustments might be done by applying a learning sequence to quantify and adjust for static or slowly varying delays between the timebases and coordinating the timebases using output of the learning sequence. The learning sequence might quantify and adjust for static or slowly varying delays and frequency drift in a communication system having a master timebase device and slave timebase devices wherein slave timebase devices are configured to adjust their local timebases to coincide with the master timebase by obtaining timing/synchronization information during one or more events, the events being communication and/or synchronization events, analyzing the timing/synchronization information to derive timing errors due to system nonidealities, and applying timing correction based on timing errors derived by the analyzing.

In a network environment, a wireless medium is reserved for transmissions. Medium reservation modifications can be requested and granted wherein a master device allocates a medium using reservations that are observed by other devices sharing the medium and a slave device complies with reservations by holding data for transmission until its reservation in time arrives by determining a reserved length of an upcoming transmitting opportunity reserved for a slave device, determining a desired length for transmitting data from the slave device over the medium, comparing the reserved length and the desired length to determine if a medium reservation modification is warranted, if the medium reservation modification is warranted, requesting, during the reserved time covered by the medium reservation, the medium reservation modification, and determining whether to grant or deny the medium reservation modification and conveying the determination to the slave device.

A method and apparatus for driving light emitting polymer (PolyLED) displays is provided. Because PolyLED displays exhibit high capacitance characteristics, pre-charge current is injected to bring the diode up to near its operating current prior to enabling the diode. Thus, time and power is not wasted charging and discharging the high capacitance that is inherent in PolyLED displays and life of the diodes are prolonged because the diodes are not required to swing the full voltage range during each cycle. In addition, since older diodes need more voltage to produce the same current thus the same light intensity as newer diodes, an embodiment of the present invention adds an adaptive power generation system that actively monitors and adjusts power as necessary in order to generate constant amount of light (i. e. , constant current) from all the diodes in the display.
